Product details
■Product Overview
The GGD AC low-voltage distribution cabinet complies with standards such as IEC439 "Low-voltage switchgear and controlgear assemblies" and GB7251 "Low-voltage switchgear and controlgear assemblies".
■Model Meaning
■Operating Conditions
Ambient air temperature not higher than +40°C, not lower than -5°C. The average temperature within 24 hours must not exceed +35°C.
Indoor installation; the alti
tude of the installation site must not exceed 2000m.
Relative humidity of ambient air does not exceed 50% at the highest temperature of +40°C, and higher relative humidity is allowed at lower temperatures (e.g., 90% at +20°C). Consideration should be given to the possibility of condensation due to temperature changes.
The inclination of the equipment from the vertical plane during installation does not exceed 5°.
The equipment should be installed in places without severe vibration and impact, and where electrical components are not subject to corrosion.
Special requirements from users shall be settled through consultation with the manufacturer.
